Fishing and like lines.

' To-qll It wuzi/concizrn:

Bef It known that I, Anrnr'n' HOLDEN ILLIr'tGWORTH, of 2 Highclere. Villas, Ben Rhydding, in the county of York, England, woolmerchant, subject of the King of Great Britainvand Ireland, have invented certain new and useful Improvements in and Relatingto Fishing and Like Lines, of which the following is a specification.

This invention relates to improvements in fishing and like lines, and has for its object means for weighting fishing lines, thereby allowing of lines of greater specific gravity being used in place of lines of less specific gravity and with such lines having been treated as hereinafter described, increased-length of cast may be obtained as compared with casts made with ordinary line of equal thickness, owing to the increased weight in relation to the thickness. That is to say a line treated in this-waywill be heavier than an untreated line of the same thickness, the advanta e of which will be appreciated by those ski] ed in the art of fly-fishing. 'Iii earryingout, my invention, while I prefer taper plaited silk linesrlmay apply the treatment to twisted silk lines or to cot-- ton or other lines whether taper or level.-

Broadly, my process of treatment consists of incorporating with the line mercury in' some form or other. This may be done either chemically or mechanically and the mercury may be either the free metal or some mechanical compound or some salt of mercury. 'l'he mercury may be applied to the line by rubbing as a'paint or ointment,

. in conjunction with a suitable medium. The

medium may consist of any oxidizin oil or any evaporating oil; instances 0 the former are linseed oiland poppy oil, and of the latter, petroleum, v

In order to make the mercury into. a suitable emulsion, paint or ointment, a certain amount of some other heavy substance may with advantage be added-calomel or vermil-ion would he suitable'for this purpose, mercury together with the calomel and a medium forming a grey amalgam or emul sion, the thickness or viscosity of which can be made as desired. Another ln'ethodof applying metallic mercury to the line 1s by chemically reducing or precipitating the I metal in the texture of the line. This may he done for instanceby applying an aqueous STATESTPATENT OFFICE.

solution ofmercuri'c chlorid and afterward treating the line with an aqueous solution ofstannous chlorid. Y

In place'of applying metallic mercury to the line either by chemical or mechanical means as above described, insoluble salts'of mercury may be precipitated in the line so salt and afterward by a compound of sulfur, as 'for'instance an aqueous solution of mercurous nitrate, subsequently treated with ammonium sulfid; calomel precipitated.

in the line by an aqueous solution of mercurous nitrate or mercuric chlorid treated subsequently with chlorid of sodium.

Any suitable solvent may be used for dissolving the mercuric salt preparatory toapplying it to the line, as for instance alcohol or glycerin; sulfur may also be applied in any convenient form, such as sulfureted hydrogen gas. Any other convenient precipitate may be used, but these are instances of many difierent ways of precipitating various mercury salts in the textureof the line, some of them being more suitable than others unaccount of the absence of deteriorating effect upon the strength of the line itself. The amount of weight which is added to a given line may be controlled by varying theamount of mercury applied.

The mercury may be incorporated in the line by submerging the line in cameo, in metallic mercury, or emulsion containing mercury in a finely divided condition'a-fter the well-known air-pump method of dressing lines. A pigment may be added to give the line any desired color. may not be dressed or water-proofed subsequently to the above outlined treatment, by

The line may or any of the usual methods. In practice, how- 'mudh as 1.00% or more may be added if desired and the result is, that for a given iveightpf line the'thickness is reduced by as much as one half, thereby enabling longer 110- .and more accurate casts to be made with a lineso treated than'the usual form. The resistance of the air is very much reduced, thereby the friction of the line on the rings ofthe fishing rod is reduced and the drag ofthe current u on the line in the water is less than with t e ordinary line, which to obtain the same weight has to be considerably thicker.

The special purpose for which this improvement is recommended is for lines for of the line for the distance which the lure or fly may be thrown.

W'hat I claim as my invention is I 1. A fishing line having mercury incorporated therewith to increase the weight of the line.

v2. A fishing line having mercury incor- V porated in the texture of the line to increase the weight of the line.

' In witness thereof, I have hereuntocset my hand, in the presence of twowitnesses. A. HOLDEN ILLINGWORTH.
